Flat fritters of wheat flour and aguapanela, dropped into a pan by the spoonful and fried in ten minutes. Four ingredients you already have, and the aguapanela is what makes them Colombian rather than a pancake.
Aguapanela is panela, unrefined whole cane sugar, dissolved in water. It is drunk on its own all over Colombia and here it is the liquid the batter is made with, which is what gives these their colour and their molasses note. The recipe's own notes explain the variations: use aguapanela and skip the sugar for sweeter ones, or plain water with sugar to taste, or water and salt for savoury ones. Thick batter, not runny. The second step is the one that matters: it has to hold on a spoon long enough to be dropped in a round, and a thin batter spreads across the pan and fries into a lace. Flour goes in a spoonful at a time until it holds. These are fritters rather than cakes despite the name. Tortas in Spanish covers a much wider range than cake does in English, and what these actually are is small rounds of dough fried in a pan, closer to a drop scone than to anything baked.
